Do the Weight Police have jurisdiction off road?

My 2015 Ram 3500 Dually 4wd with snow plow pack and 14,000 GVWR had a piece of paper in glove box that said "this truck is not recommended to carry a truck camper". another person on this forum also had the same thing. We searched and found the snow plow pack caused this notice.
The snow plow pack only included a transfer case skid plate and a larger alternator.
we assume they don't want you carrying a camper while your plowing snow.
